I'm seriously considering three options at the moment as it seems that Canon will not be releasing any new body till september this year.
1. Sell 30D upgrade to 40D - though it's new features don't excite me after seeing what a D300 can do. (D-Lighting/weather sealed/ 51 AF / 3D tracking/ fine tune focus adjustments and more)
2. Sell 30D and 2 lenses (10-22 and 24L) upgrade to a mint 1DMKIIn from a friend ($2k)
3. Sell all of the Canon system in my sig and shift to 2 D300's and 5 new lenses and 2 SB800 flash guns. (I will save $500 with this route)
